The point of the post was to show you how they came to R52k, it had nothing to do with "people like you". I can click on the expand arrows to see the details of how it was calculated, but that's not for general consumption.
I'm a vitality member, use their short term insurance and I have the credit card. My rewards statement says they paid me R52k in 2018. I'll definitely be joining the bank too. If you put a bit of effort in, the rewards speak for themselves.
